I am working on a simulation project in which I am asked to investigate Ansys Aim. I am told to start with doing analysis on fourbar mechanism and then find out the limitations of Ansys Aim. So I had a few doubt and following are my question: 1) May I know why did Ansys design a software Ansys Aim despite having a very user friendly Ansys workbench and it's other softwares. 2) What do you think are the limitations of the software?(This will be helpful for me to add in my project too.). Because I didn't find much resources for Aim. 3) comparison between Ansys and Ansys Aim?
